Get control over the shared contents

Issue Summary

How can I set up and control the contents which should be posted on facebook? Is it possible to do it like the "share" function: with text and picture?

My setup and the background of the question: After posting a node of a certain type, the facebook stream module should be take care, that the node content is posted to facebook. The main thing works (the posting per se works), but it would be really important that the posted image goes within the facebook message. Is this possible? How can i get control over the streamed contents?
